Answer:
It's the Xinhai Revolution.
Step-by-step explanation:
The last Chinese emperor had six years old when the Revolution came to overthrow him. Until that moment, China had been ruled by the Qing Dynasty since the 17th century, but it was clear that they didn't make a good government. The lack of development and the failed treats with foreign countries brought disgrace and death to China, a good example is the Opium War whose the Quing Dynasty was not ready to confront. Then, the revolutionaries decided to overthrow this kind of government (the Monarchie) and put a Republic instead.
